Method Detail

requestPowerOff

public static boolean requestPowerOff(boolean allowAutoOn)

Requests that the Device power down.

This method may return false if power down is not possible as the
serial port is owned by an application. This prevents events such as
auto shut-off from shutting the handheld down while it is synchronizing
with the desktop.
